20K hours later seagate DMs

[Soulkeeper]

The last 2 days my system was hard locked in the morning.
Then on boot 40 pending bad sectors and tons of I/O errors.

So now both my 3TB seagate DM series have bad sectors (the first had a single on purchase).

you'll notice the first one is made in thailand (1 bad sector)
the second made in china (40 pending)

Are there any 1TB/platter 7200rpm drives without problems ?
my gut tells me that pmr tech is struggling at 1TB/platter

I think both the Toshiba and HGST 1 TB/platter drives at 7200 rpm seem ok so far reliability wise.

 

[Soulkeeper]

I think i'd jump on the HGST helum drives if they weren't so expensive

 

[Data-Medics]

Unfortunately that's the price of quality. Anything bigger than 2Tb Seagate is absolute junk. I think they are putting their R&D money into SSD technology at this point and are willing to sacrifice their reputation in the HDD market for the time being. Don't be surprised if they start using the LSI or Sandforce names to sell SSD's they make in the future, they already own those companies.

Seagate is crap. I only recommend HGST drives at this point. Well worth the price premium for the average home/small business user.

Can confirm they are quite reliable. I have 4 3TB Toshibas in raid 10 with about 11k hours of near continuous run time. (stop/start is what tends to kill drives faster though).

I have some 1TB WD blacks with similar hours and those are pretty reliable too. I added another raid 10 array with 4 WD reds (used) that are about 6-8k hours and so far so good with those as well. The reds had a rough start when they first came out and had lot of DOAs but they seem more reliable now. TBH I only got these because it was a good deal on another forum. I did have one that died in transit but got a warranty replacement and all was good.

I don't even touch Seagate anymore. I can't say I had bad luck with them myself, but just looking at statistics makes me not even consider them. I guess if they were on a super sale and I needed a cheap raid 10 where I am not too worried about the data I'd buy a couple but it's not like they're that much cheaper than the better alternatives.

looking at how long it lasted here.
"You purchased this item on November 23, 2012"

essentially 24/7 power on since then ~2.5yrs
so it survived their 2yr warranty atleast

noticing that the exact drive costs $85 now, then the wd red pro costs ~$170
What's odd is that this was a backup drive, I hardly ever used it (weekly backups).
Considering it lasted half as long as the warranty on a drive that costs 2x I literally got what I payed for :/

I just purchased a 5TB toshiba (made by hgst)
1TB/platter 3yr warranty
wish me luck

 

[VirtualLarry]

I bought a 5TB Samsung (made by Seagate, obviously), "D3 Station" external desktop HDD. It was on sale for $124.99 @ Newegg last week.

My intended use is for backup. Hopefully it won't fail too early.

WD owns HGST, but, according to the deal, they (HGST) sell their own stuff.
Toshiba makes their own HDs as well, but they got some tech from WD to make 3.5" HDs.
So, HGST only makes drives for HGST.
But, Toshiba has some of HGST's tech, but, they can't call it HGST.
In other words, Toshiba makes all their stuff.

ahh I just read "Note: Designed and manufactured by Hitachi's Deskstar design team." on http://rml527.blogspot.ca/2010/12/hdd-platter-database-toshiba-35.html
I guess that was for the ABA drives, maybe not ACA ones.
I doubt they even know who makes what
The box had atleast 2 errors on it "64MB cache" and "made in china"
it's 128MB cache and made in philippines apparently

here's to hoping the reliability is similar to HGST atleast, the performance is atleast as good as the seagate (206MB/s hdparm -tT)

 

[WhoBeDaPlaya]

I've been running HGST drives in my fileserver for the longest time.

Heck, I still have some of the industry's first 1TB drives still running all these years later, pretty much 24/7/365, with nary a reallocated sector or uncorrectable error.

knock on wood, i've got 12 2TB HGST sata drives in raid-50 for heavy (full image) veeam backups nightly, plus system image (BESR) of 50+ desktops on the weekend. When the raid box is not writing, it is reading to Offsite backup. Been 3 years - zero drive failures or smart warnings so far!

Of the two D3 Station 5TB externals I purchased and shucked, one failed while formatting and was extremely loud. My first ever DOA HDD. The other drive works very well. So make sure you put it through the works first.

seagate was crap, they're getting better

Which Hard Drive Should I Buy?

All hard drives will eventually fail, but based on our environment if you are looking for good drive at a good value, it’s hard to beat the current crop of 4 TB drives from HGST and Seagate.

Even though HGST still retains the crown, it is foolish to think of brands/companies in terms of absolutes. The HGST Deskstar that has such a stellar reputation right now was a brand once notoriously referred to as the "Deathstar"

Just a little update... seems like Seagate is also crippling the firmware on Samsung externals to prevent them being used as SATA internals.

The first drive outright refused to format. The second drive will quick format, but can't get through a full format. Sometimes it's recognized, sometimes it isn't. I'll reassemble the enclosures and test them before sending them back to Newegg.

Guess it's time to switch to WD-HGST and Toshiba-Hitachi. Seagate no longer wants my clams.

EDIT: I reassembled both. One works the other has major SMART errors: reallocated/uncorrectable sectors and LBA. Damn.

Before I put any drive into production I always do a full dd read and dd write. This ensures that every sector is read and written to. If I get any weird errors in dmesg or it completely fails, I RMA it.

I used to just pop it in the raid array and rebuild, but I learned from that mistake. Thankfully never lost data from it, but had scary moments.

+1 I do a full sector scan, full zero fill, another full sector scan, another full zero fill.
If a single damned thing pops up in the SMART attributes, it's junk.

I have two in RAID 0, no issues so far.

I think people are too harsh in opinion of these drives, as they are not designed for 24/7 usage.

They are rated for 2400 power-on hours and 300,000 load/unload cycles where-as the NAS drives are rated for 8760 hours and 600,000 load/unload cycles.

This is interesting.
Thinking about what Red Squirrel said, I decided to mess with this drive a bit more.
I took the hd and updated the fw, then wrote/read the entire disk 4 times with badblocks (40hr run).
Now the pending sectors went away and it passed the smart test
http://sterlingdesktops.com/smartctl-logs/sdc-04-14-15a.txt

apparently there is nothing wrong with it, but for whatever reason it was spitting out I/O errors on boot, had fs errors, and failed smart.
I expected those pending to become reallocated sectors.
It's worth noting that I had a power outtage recently due to some welding
